直流接触器作为应用广泛的电气开关之一，其生产和需求数量巨大，在正常使用过程中，电磁铁线圈一直通电工作，产生电磁吸力，保证铁芯和衔铁吸合，带动动、静触头闭合，接通电路。在上述过程中，线圈本身存在电阻，持续消耗电能，这是直流接触器主要的使用成本之一，浪费了大量的能源和财产，因此，如何降低直流接触器的工作耗能，是研究直流接触器的关键点和重难点。直流接触器永磁操动机构是一种在传统直流接触器电磁操动机构基础上发展而来，将电磁操动机构和永磁铁相结合的混合型操动机构，不单单使用原有的电磁吸力和弹簧反力作为铁心吸合与分离的动力，而是加入了永磁铁对铁心的吸引力，采用储能电容充放电提供合闸、分闸电力，通常称之为“电磁操动，永磁保持，电子控制”。在分、合闸运动过程中，电磁吸力，永磁吸力与弹簧作用力共同作用，在稳定工作过程中，采用永磁吸力代替之前的电磁吸力，保持衔铁与铁芯心的吸合状态。一则，永磁操动机构大量节约了保持线圈的电能消耗，环保节能。二则，永磁体保持吸合与电磁吸合相比，噪音低，无污染。三则，永磁操动机构剔除了电磁机构中一系列复杂繁琐锁扣保护装置，大大提高了接触器操动机构的工作可靠性，降低了生产工序和成本，减小了接触器的体积。 [1]

80年代后，各国研究交流接触器电磁铁的无声和节电，基本的可行方案之一是将交流电源用变压器降压后，再经内部整流器转变成直流电源后供电，但此复杂控制方式并不多见。
真空接触器：真空接触器是接点系统采用真空消磁室的接触器。
半导体接触器：半导体接触器是一种通过改变电路回路的导通状态和断路状态而完成电流操作的接触器。
永磁接触器：永磁交流接触器是利用磁极的同性相斥、相吸的原理，用永磁驱动机构取代传统的电磁铁驱动机构而形成的一种微功耗接触器。3TH40220XL2
